I`ve had good results with any I could get. Right now I`m using CCI 400`s.
@ I was going to say most anything except cci 400 for my bolt action pressures. Typically I am using CCI 450 or BR4's, again in a bolt action. If I was loading some lower pressure loads, I would have no problem with the thinner cup CCI 400. Price & availability of primers can change our thought process for primer selection.
